Importance of cattle biodiversity and its influence on the nutrient composition of beef

Livestock make a substantial contribution to achieving food and nutrition security due to various factors including the high nutritional quality of animal-source foods. Conservation and sustainable use of cattle genetic resources are important due to the multiple benefits provided by local breeds. These benefits include multiple direct uses, additional market value provided by specialty products, social and cultural roles, and adaptations that local breeds have to climate and diseases in harsh environments. Meat composition varies across cattle breeds. Whereas genetics play a role in this variation, management practices, such as diet, and other environmental factors also affect nutrient composition. Compositional data for cattle breeds have been added to the FAO/INFOODS Food Composition Database for Biodiversity. The database is publicly available and has value for use by researchers, nutritionists, producers, the general public and other stakeholders. More compositional data, including amino acids, minerals, and vitamins, are needed from local breeds in order to understand better the nutritional benefits of sustainably managing animal genetic resources

Importance and use of reliable food composition data generation by nutrition/dietetic professionals towards solving Africa’s nutrition problem : constraints and the role of FAO/INFOODS/AFROFOODS and other stakeholders in future initiatives

Despite the rich biodiversity of the African continent and the tremendous progress so far made in food production, Africa is still struggling with the problems of food insecurity, hunger and malnutrition. To combat these problems, the production and consumption of nutritious and safe foods need to be promoted. This cannot be achieved without reliable data on the quantity and quality of nutrients and other components provided through these foods. Food composition data (FCD) are compiled as food composition tables (FCT) or food composition databases (FCDB). These are subsequently used for a variety of purposes, ranging from clinical practice, research, public health/education, food industry to planning and policy, as well as nutrition monitoring and surveillance. To perform these functions effectively, the importance of reliable FCT/ FCDB cannot be overemphasised. Poor quality FCT/FCDB have serious consequences on the health of the population, and provide skew evidence towards developing nutrition and healthrelated policies. The present paper reviews different methods to generate FCT/FCDB, their importance and use in assisting nutrition/dietetic professionals in solving Africa’s nutrition problems; current status of FCT/FCDB generation, compilation and dissemination in Africa, constraint to their use by professionals and the role of FAO/INFOODS/AFROFOODS and other stakeholders towards improvement and future initiatives. The information provided will create awareness on the need for up-to-date and high-quality FCT/FCDB and facilitate the identification of data gaps and prioritisation of future efforts in FCD generation, compilation and dissemination in Africa and subsequent strategies for the alleviation of the food and nutrition problems in Africa.https://www.cambridge.org/core/journals/proceedings-of-the-nutrition-societyam2020Animal and Wildlife Science

Overcoming Dietary Assessment Challenges in Low-Income Countries: Technological Solutions Proposed by the International Dietary Data Expansion (INDDEX) Project

An increasing number of low-income countries (LICs) exhibit high rates of malnutrition coincident with rising rates of overweight and obesity. Individual-level dietary data are needed to inform effective responses, yet dietary data from large-scale surveys conducted in LICs remain extremely limited. This discussion paper first seeks to highlight the barriers to collection and use of individual-level dietary data in LICs. Second, it introduces readers to new technological developments and research initiatives to remedy this situation, led by the International Dietary Data Expansion (INDDEX) Project. Constraints to conducting large-scale dietary assessments include significant costs, time burden, technical complexity, and limited investment in dietary research infrastructure, including the necessary tools and databases required to collect individual-level dietary data in large surveys. To address existing bottlenecks, the INDDEX Project is developing a dietary assessment platform for LICs, called INDDEX24, consisting of a mobile application integrated with a web database application, which is expected to facilitate seamless data collection and processing. These tools will be subject to rigorous testing including feasibility, validation, and cost studies. To scale up dietary data collection and use in LICs, the INDDEX Project will also invest in food composition databases, an individual-level dietary data dissemination platform, and capacity development activities. Although the INDDEX Project activities are expected to improve the ability of researchers and policymakers in low-income countries to collect, process, and use dietary data, the global nutrition community is urged to commit further significant investments in order to adequately address the range and scope of challenges described in this paper

Dietary exposure and health risk assessment for 14 toxic and essential trace elements in Yaoundé: the Cameroonian total diet study

<div><p>Dietary exposure to trace elements (aluminium, antimony, barium, cadmium, lead, nickel, vanadium, copper, manganese, molybdenum, germanium, lithium, strontium and tellurium) was assessed by the total diet study (TDS) method. Sixty-four pooled samples representing 96.5% of the diet in Yaoundé, Cameroon, were prepared “as consumed” before analysis. Consumption data were sourced from a households’ budget survey. Dietary exposures were compared with health-based guidance or nutritional values and to worldwide TDS results. The health-based guidance value was exceeded by ≤ 0.2% of the study population for aluminium, antimony, barium, cadmium, nickel and vanadium. For lead, the observed 95th percentile of exposure (3.05 µg kg⁻¹ body weight day⁻¹) equals the critical value considered by JECFA for cardiovascular effects; therefore, risk to health cannot be excluded for certain consumer groups. The population at risk of excess intake for manganese, copper, molybdenum and nickel was considered to be low (≤ 0.3%). The prevalence of inadequate intake was estimated at 5.9% for copper and was nil for molybdenum. Due to the lack of toxicological and/or nutritional consistent data to perform a risk assessment, dietary exposures to germanium, lithium, strontium and tellurium were provided as supplementary data. The food groups highest contributors to exposure were “tubers and starches” for aluminium (27%), lead (39%) and copper (26%), “cereals and cereal products” for cadmium (54%) and manganese (35%), “fruits, vegetables and oilseeds” for barium (34%), molybdenum (49%) and nickel (31%), “beverages” for antimony (27%) and “fish” for vanadium (43% – lower bound). Measures should be recommended to maintain low levels of exposure before the problem could become an important health or trade issue.</p></div
